MOVING SIGN.

Application led September 28, 1926.V Serial No. 138,228.

Our invention relates to improvements in signs, which are moved bymachinery in a series, usuallyin a straight line, and it consists in thenovel features, which are hereinafter described.

One of the objects of our improvement is-to have the mechanism of amovingsign compact, especially in the direction of the thickness ordepth of the sign-frame, i. e. the direction, which is at right anglesto the plane of the moving sign.

Another object of 'our improvement is to have each sign face forwardlyall the time while travelling in opposite directions VA with the series,thereby reducing the number 'of signs, which are not exposed to view. Afurther object of our improvement is to have our moving sign simple,durable and inexpensive.

Other objects and advantages will hereinafter appear.

TWe attain these objects by the mechanism. one form of which isillustrated in the ac any mechanical equivalent or obvious modificationof the same.

In the drawings Fig. 1 is a section on the line 1-1 of Fig. 2,

Fig. 2 is a front elevation of our moving sio'n.

:The middle portion of the sign-frame is shown as broken away in bothFigs. 1 and 2. Fig. 3 is a section on the line 3-3 of Fig. 4.

Fig. 1 is a front elevation of one of the sign pockets.

F ig. 5 is a fragmentary topview or plan of our moving sign, showing theplacement spring, which is hereinafter described, in its forwardposition, and showing the sign pockets in a different phase of motionAthan in Fig. 2. y

Like numerals refer to like parts through- `out the several views. i

11 designates built up of longitu-dinalchannels 12 and 13, shown inFg.p2,y and end channels 111, shown in Fig. 1.V

Vertical bearings for said shafts are omitted in the drawings, yfor thesake of clearness.

Sprocket wheels 17 and 18 are secured to said shafts and 16respectively, to mesh with an endless chain 19, which is shown in a signframe which may be shafts 15 and 16 are shown as revolvably mounted onsaid frame 11; the

Fig. 1 and is omitted in Fig. 5, for the sake of clearness.

Asshown in thek drawings, `the chain 19 is arranged to travel from rightto left at the front of the sign and return from left to right at therear of the sign.

`The shaft 15 is shown as having mounted at the-upper end thereof a spurgear 20, which is oneof a train of gears for transmitting motion to saidshaft 15 from a suitable motor or line shaft.

Sign pockets 21 are shown in Figs.' 1, 3 and 5 as having each thereontwo pins or projections 22 and 23: one pin 22 on the ,front thereof andone pin 23 on the rear thereof.

The pins 22 are engaged by the part of the chain 19, which travels atthe front of the sign, and the pinsk 23 are engaged by the part of thechain 19, Vwhich travels at the rear of the sign.

Guide bars Qlfand 25 are secured to the channels 12 and 13 respectively,and serve to keep the series of sign-pockets 21 at the front of the signseparated from the series of pockets 21 at the rear of the sign and tokeep said pockets 21 in engagementwith the chain 19. n

The pins 22 of the series of pockets 21 at the rear of the sign and thepins 23 of the` series of pockets at the front of the sign slide on theguide bar 24.

VThe frame 11 has secured thereto at the front thereof cover plates 26and 27 to shield` from viewthe sprockets 17 and 18, also the extremepositions 'of the pockets 21, and, at the rear thereof, lug plates 28and 29, which have thereon openings 30, for connecting the sign to anyvertical structures, such as walls or posts of buildings.

Placement springs 31 and 32 are provided, to move each sign pocket 21from the front series to the rear series and vice versa, as said pocket'reaches the end of the series, thereby disengaging from the chain `19one of the 'pins 22 or 23 on said pocketand en-` gaging the other pin.`

The placement spring 32 is shown -in Fig.

`1 as secured by means of a rivet or screw ings for the sake ofclearness.

The placement spring 32 is shown ein, Fig. in its forward position afterhaving moved one ci said pockets 21 irom the series oi pockets attherear of the signs to the seriesk at the front of the signs; thepin`23 of'tliis' pocket has been disengaged by said spring; 32 from therear part of the chain 19 and the pin 22 thrown intoengagement withV thefront part of said chain.

The guide bars 24 and 25 are shown as shorter than said series ofpockets 2l, thereby leaving` room for each pockety 21 at the end oi eachseries to be moved by said springs 31` and 32 from the front to the rearof the sign-frame and vice versa;

he sign pockets 21 are shown in Fig. 3 as having therein room for signsor advertisements, which are designated in Fig. 2 by the letters A, B,C, D, E, and F.

An opening 34 is provided in the front Wall of each sign pocket 21' forsaid'y signs or` advertisements to Ybe displayed therethrough.

A door 35 is shownin Fig 2 as covering an opening in the top of thechannel 13 of the i'rame 11, for readily removingsigns or advertisementsfrom thelpockets 21 and for inserting said signs tliereinto.

The placement springs 3l and 32 are shown as sinusoidal in shape; butthey may also have any other shape, it desiredi Many other-changes maybe made'in the details ot' our moving' signs-Without departing from themain scope ot` our invention, andparts ol our invention may be usedWit-hout: other parts.

le do not, therefore, restrict ourselves to Vthe details as shown in thedrawings, but We intend to include also all mechanical equivalents andobvious modiiications of the same Within the scope of our invention.

lVhereife-r the term moving 'sign77 is used in the speciiicationand'claims, it is meant to designate a series or series of moving signs.
